docs(static-deploy): bump version of actions/checkout and actions/upload-pages-artifact

[DaleSeo]

Description

On the Deploying a Static Site in the GitHub Pages section, I've updated the yml example to use the latest version of the actions/checkout and actions/upload-pages-artifact actions.

Here's the workflow run that has been tested with the latest versions: https://github.com/DaleStudy/vite-vanilla/actions/runs/6646941535
